Software output is required for this assignment. 1. Malevolent Uniforms in Football. Do teams with malevolent uniforms get more penalties? Participants with no knowledge of the teams rated football jerseys on characteristics such as timid/aggressive, nice/mean, and good/bad. The averages of these responses produced a "malevolence" index, with higher scores signifying impressions of more malevolent (evil-looking) uniforms.

a. Use Statkey to generate a bootstrap distribution of the correlation between penalty yards and uniform malevolence using the data on 28 NFL teams in Malevolent Uniforms (ZPenYds as a function of NFL_Malevolence - this data set is preloaded in StatKey). Find a 90% confidence interval for the correlation using the percentiles method (generate at least 3000 samples). Include a screen shot of the graph for this distribution with your assignment.

90% CI: _____________

b. Interpret the confidence interval.

c. What is the standard error of the bootstrap distribution?

SE = ___________________

(From Section 5.2) Use the original sample correlation and this standard error to compute a 90% confidence interval for the correlation using z* = 1.645 for a 90% confidence level from a normal distribution.

The formula for the confidence interval is: (sample statistic) z*SE, or in this case: r z*SE

90% CI: _________________

d. Why is the normal-based interval somewhat different from the percentile interval in this case?

plz send graph too
